To all whom it mal concern,-

Beit known that we, THOMAS M. STAcK and WALTER R. PE-CK, citizens of theUnited States, residing at New Milford,:county-of 5 Litchfield, State ofConnecticut, have invented a new and useful Composition of Matter to beUsed for the Removal of Paint, Varnish, &c., from Woodwork Preparatoryto Refinishing, of which the following is a specifica- [0 tion. Theobject of this invention is to provide a composition that will quicklyefiect theremoval of either paint or varnish from surfaces which fromlong use or abuse have become marred to such an extent'as to makerefinishing necessary, it being required under such conditions that allcoats of paint or varnish composing the original finish down to the barewood be removed before the refinzo ishingprocess can be commenced. It isfurpurpose thatit shall be perfectly safe in use in that it shall notinjure the hands of the party using it and that there be no fumesarising therefrom injurious to health, and, furthermore, that it shallnot discolor or raise 1 the grain of the wood to which it may beapplied.

We are of course aware that various meth- 0 ods have heretofore beenemployed for the removal of paint and varnish, among'whichmay bementioned compositions including as ingredients caustics, potashes,850., whose use is objectionable, owing to the fact that seriouslyinjure the hands if brought into contact therewith, and, furthermore,that the inhalation of fumes arising therefrom is seriously injurious tothe health of the user.

they are destructive to animal tissue and will These objections are, infact, soserious as to.

four gallons; alcohol, (wood or grain,) four gallons; benzole, fourgallons; acetone, three gallons; sixty-two-degree benzin, three gallons.These ingredients are to be thoroughly mingled by'agitation.

In using the above-named compositional coat of the composition isapplied to the surface to be refinished, using for the purpose a brushor a cloth well saturated with the composition. The composition isallowed to remain on the surface until it assumes agelati be removed.The operator may then with awide-bladed spatula or putty-knife removethe entire coating. The surface should then be washed ofi to removeanyof the softenedcoating that may not have been removed by the spatula,using a cloth saturated with I either benzin or wood-alcohol, as may bepreferred. This leaves the surface perfectly clean and after beingallowed to dry it is ready for refinishing. Should the old coating onthe surface tobe refinished be a light one and not specially refractory,it may be readily removed by a brisk rubbing with a cloth well saturatedwith the composition. Thecomplete removal of theold coating'willbe'apparent by the appearance of the bare'wood,

after which the surface may be washed off as above describedwith'eithe'r benzin or woodalcohol. If an old coating is to be removedfrom moldings or from any surfaces containing crevices, it will be foundpreferable to apply the composition with a brush rather than a cloth, asthe latter will not enter thecrevices as well. i i

We wish it distinctly understood that our invention is not limited toany exact proportions of the ingredients enumerated- As stated above,either grain-alcohol or wood-alcohol may be used. In practice'we have 1found wood-alcohol perfectly effective. -Furthermore, while wepreferably use the ingredients stated in their purest form their use inthe purest form is not essential to the operativeness of thecomposition, as the ingredients may be used in crude form instead ofrefined, if preferred.

We are of course well aware that benzin and wood-alcohol have been usedas ingredients in various cleansing and removing compositions and onlymake claim to these ingredients when used in connection with amylacetate, benzole, and acetone.

Having thus described our invention, We claim The herein-describedcomposition of matter consisting of amyl acetate, alcohol, benzole,acetone and benzin substantially as described and forthe purposespecified.

In testimony whereof we affix our signatures in presence of twowitnesses.
